' Application filed. May 8, 1917. Serial No. 167,229.

To all whom it may concern:

Be it known that T, HENRY W. KAKASKA, a citizen of the United States, residing at Mandan, in the county of Morton and State of North Dakota, have invented a new and useful Spark-Plug Tnt'ensifier, of which the following is a specification.

The present invention relates to a spark I plug attachment or intensifier, and aims to provide a device of that character adapted especially for, use upon old or sooted' spark plugs to renew the life and efliciency thereof.

A further object of the invention is the provision of a spark plug intensifier of extremely simple and inexpensive construction, which can be cheaply manufactured,

and which will serve its ofice in a thoroughly practical and efiicacious manner.

' With the foregolng and other ob ects in 'view which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of'construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed can be made Within the scope of what is claimed, Without departing from the spirit of the invention.

The invention is illustrated in the accompanying drawing, wherein Figure 1 a side elevation of the attachment as applied to a spark plug.

Fig. 2 is a plan view of the device.

In carrying out the invention, there is provided an elongated strip or plate 1 of fiber or other suitable insulating material having engaged therethrough near one end, a bolt 2 fastened to the plate by means of a nut 3 thereon, and bearing a binding nut 4 to clamp the terminal of the conductor 5 The conductor is applied to the binding post provided by the bolt 2 and nuts thereon, instead of being attached to the spark plug.

A metallic strip 6 is riveted between its ends, as at 7, to the plate 1 near the other end thereof, and has a protruding flat flush terminal 8 to be clamped to the spark plug 10 in the manner of an ordinary conductor,

astride the binding post or central conductor of the spark plug. The inner terminal 11 of thestrip 6 is preferably tapered, and bent at an acute angle from plate 1 and is spaced slightly from the binding post to provide a spark gap, whereby the device will serve its oiiice of an intensifier, to renew the life of the plug. The strip 6 is attached to and support it by the plug, while the plate 1 is supported from the strip 6, the binding post being in turn supported'by the plate. This provides an extremely simple, yet sufficient device for the intended pur poses. The terminal 11 beingspaced from the binding post, provides a spark gap which will intensify the sparks produced by the plug.

The device above described embodies, briefly considered, a spark plug 10 having a binding member 50 thereon, and a metal strip 6 having a flat end 8 the opposite faces of which are engaged directly by the plug 10 and by the binding member 50 to afford an increased contact. An insulating plate 1 is overlapped on the strip 6, a securing device 7 uniting the plate and the strip. A binding post 2' is carried by the outer end of the plate 1, the outer end 11 of the strip 16 being disposed at an acute angle to the plate 1 to point toward the post 2. The

' plate 1 terminates, as shown at 51, at the periphery of the post 10 and bears thereagainst, to prevent a swinging of the plate 1 on the securing device 7 and to prevent a shifting of the outer end 11 of the strip 6 with respect to the post 2, should the secur-- ing device 7 loosen its hold.

Having thus described the invention, what is claimed as new is The combination with a spark plug having a binding member thereon, of a metal strip having a fiat end the opposite faces of which are engaged directly by the plug and by the binding member to afford an increased contact; an insulated plate overlapped upon the strip; a securing device uniting the plate and the strip; and a binding post carried by tlie outer end of the plate, the outer end of the strip being disposed at an acute angle to the plate to point tilt toxavard the post, the plate terminating at In testimony that I claim the foregoihg the periphery of the post and bearing there as my own I have hereto afiixed my signaagainst to prevent a swinging of the plate ture in the presence of two Witnesses.
